Vulcan in a School Kitchen

Dear CWT Team,

The steam convection oven has greatly improved since the installation

of the Vulcan. The water is injected via the pipe in the centre of the

heating coils and a fan inside the coils blows the water through the coils

and comes out as steam. The operating temperature of this device is

350F (180°C). The white material you see on the coils is a powder

coating that is easily removed with a wet cloth. No more chemicals are

required to clean the convection oven.

However, we have noticed even greater results in the school kitchen,

which was previously using a traditional water softening system. But all

in all, we can confirm the effectiveness of the Vulcan treatment, which

means less work for the maintenance staff.

The Vulcan unit installed on the entire building system has also been

extremely effective. No more rusty water after weekends and Christmas

break. The next Vulcan will be installed on the other school buildings,

which are around 20 – 25 years old.

The last Vulcan unit is installed on the main cooling tower – we have

had nothing but positive news in regards to this installation. We will be

seeing more orders coming from this customer very soon.

Best Regards

Arne Vestad

Grease Trap in a Kitchen

3 Months Test

To alleviate the overflow of drainage out of the basket due to oil balls in the grease trap under the

sink of the counter in the cookery on the fifth floor of the building. Also, to save the administrative

and maintenance expenses by reducing the periodical cleanings used to be conducted several

times a year. Pipe Size: 50A | Vulcan Model: Vulcan 5000

June 13th | Before Vulcan installation

Usual level of standing water.

June 17th | Installation of Vulcan

For treating water in the cookery on the fifth floor, Vulcan is

installed on the vertical piping in the warehouse where the

nearest main water pipe is exposed. The effectiveness of the

Vulcan appears in all the service water on the fifth floor that is

supplied through this piping.

Verification of the effectiveness

Grease trap under the countertop

The status of the grease trap upon installation of the Vulcan

was confirmed, and the changes of the statuses were

observed for approximately five months from the start of

the operation. In almost all cases, the effectiveness can be

confirmed through the observation for about 3 months.

September 12th

Sept. 20th - Before cleaning

Sept. 20th - After cleaning

The portions usually being contacted with

the treated water are cleaned easily with a

water flow from the tap.

The status after being used without cleaning

since the installation in June (no adhered

materials are seen on the portions usually

contacting with water).

Grease trap was cleaned with water flow

under the sink.

Similar effects have been reported at drainages in food factories, restaurants and kitchens. Many Vulcan installations showed that

the treated water had substantial cleaning effect even with extremely reduction of conventionally used detergents. There were

even some cases where the use of detergent (such as cationic detergent) causes a buildup of a thin film of dirt. Cationic detergents

should not be used. With the portions that do not contact with the treatment water, this effect cannot be expected. Vulcan has no

effect of breaking or resolving solids in drainage. Although the Vulcan has no disinfection effect, its prevention of dirt from adhering

to the basket and the net contributes to the reduction of mold‘s food source.

TA Truck Stop — Moriarty, New Mexico

USA

Moriarty Travel Center

Here in Moriarty N.M. we have extremely hard water.

In our truck stop we have to always clean up after it.

The showers are a particular problem. From clogged

shower heads, to constant cleaning and scrubbing to

keep them clean.

It also wreaks havoc with the boilers and water

heaters. After Andy and Vulcan Water Products

installed the S100 unit on the main line, we noticed

real soon, that the showers were becoming cleaner,

and the discoloration in the water was gone too!

In our Country Pride restaurant, they noticed a

dramatic change in the color and clarity of the iced tea

and coffee, cleaner, spotless glassware and dishes,

and the ice machine makes clean ice! We are very

pleased with the results. Thank you Vulcan!

Reference Letter

Dear Sir,

our Mövenpick Restaurant opened in January 2000. After a short period of time we noticed a high level

of limescale developing on the ice-cream makers. These calcification’s could only be cleared bit by bit

which is a time consuming process. To avoid potential losses, a short-term limescale filter was installed.

The operating time of this filter is limited however and thus resulted in high costs.

At a trade fair visit we consulted the company Christiani Wassertechnik GmbH about other possibilities.

We installed the limescale converter Vulcan 5000 and the ice-cream makers have been functioning

smoothly for 10 months now.

The limescale, which accumulates especially in the crushed ice makers, can now be easily removed as

it is converted into fine-grained structures.

We wish the company Christiani further success with their excellent products.

Yours Sincerely,

Marcel Charrier

Water Treatment System VULCAN

Dear Mr Christiani,

We are a company in the adhesives industry originating from the production of gelatin.

Traditionally a high amount of water is required for the extraction process to produce

gelatin. For this we have our own deep wells from which the required water

is drawn. Due to the area‘s geology, the ground water is relatively hard which

inevitably results in thick layers of adherent limestone in the tanks. Some of which only

were removable by using chemical substances. The water heater was also subject to

relatively quickly calcification.

To remedy this, we have already taken one of your Vulcan systems into operation in the

central hot water supply. We were stunned by it‘s results, especially as the opinion about

this kind of water treatment systems is very much divided.

The physical treatment of the water by Vulcan caused a significant reduction of adherent

Vulcan for Grease Traps

3 Months Test Report

KIYOKAWA Plating Industry in Fukui, Japan

Vulcan has a trouble free design and easy installation. The LED light

always blinks dependably as it shows the processing conditions.

I have compared the state of the grease trap before and after

installing the Vulcan. Before installation, I noticed strong odors

when opening the hole. When I opened the hole one month after

the installation, no such odors were present.

As for the cleaning intervals, monthly cleaning may now not be

required. The effect and cleaning intervals of Vulcan will require an

annual observation, however, I believe the amount of cleaning will

be reduced remarkably.

The Vulcan S25 device has been installed on the machine

responsible for washing the white containers which have

barcodes located on the side.

Before installing the Vulcan unit, the scanning machine

could not read barcodes due to scale incrustations. Now

after installed Vulcan, the machine is able to read these

bar codes correctly. Bigard is now saving on maintenance

costs and reduced time spent on cleaning the washing

machine and white boxes.

Dear Sir,

We have been using your Vulcan-Impulse-Technology for over a year with great

success.

Despite the use of chemicals during the pasteurisation of vacuum-packed

sausages such as hard water stabilizing agents and corrosion inhibitors, heavy

scale deposits accumulated in the pipes and the holding tanks which could only

be cleared through intensive chemical purification several times throughout the

year.

Six months following an intensive purification and the installation of your Vulcan

technology, only very few deposits in the warming zone and none at all in the

cooling zone could be found.

These deposits need now only to be cleared once a year at a considerable lower

cost.

We wish you further success with your technology against scale and rust

Holiday Resort Lombok

Indonesia

Reason for Vulcan installation

Engineering had to manually remove scale from pumps,

valves, kitchen equipment and from the 102 individual

electric hot water heaters every 6 months because the

property relies entirely on hard ground water which caused

signifi cant scale issues year after year.

Holiday Resort Lombok, Indonesia

Pools / several Food and Beverage outlets

www.holidayresort-lombok.com

Result installation of Vulcan S25

The Chief Engineer reported after an initial 6 months

following installation of the electronic anti-scale system

Vulcan S25 they were able to easily flush out already

dislodged scale from each tank heating unit – instead of

scraping away hard scale from the elements. After a second

inspection the units were found to be almost entirely free of

scale. Future inspections have now been reduced to annual,

random inspections only – which is felt to be suffi cient to

ensure overall domestic water piping system cleanliness.

Anti-Scale System Vulcan S25 installed

Inspection after 6 months

One of the water heaters at a Sea View Bungalow (photo)

was opened for inspection and showed much dislodged scale

particles at the bottom of the tank, with some easily removed

soft scale still present on the element only. This water heater

unit had not been scheduled for random inspection since

installation of the Vulcan unit at the Resort.

Additional benefits reported

The General Manager and CE reported that shortly after the

Vulcan had been installed, the linen being washed at the

inhouse Laundry plant was softer and whiter. In addition,

Food and Beverage staff reported brighter glass ware

with the detergents working much better. Housekeeping

staff reported that the usual white spots on bathroom tubs,

counters and floors had entirely disappeared and that outlets

of showers and taps needed no longer special attention with

only basic wiping being suffi cient to maintain their shine.

The little remaining scale is soft and easily fl ushed

out since installation of the Vulcan Anti-Scale System.

Re: physical water treatment unit Vulcan S100

Dear Mr. Christiani,

Munich

We are pleased to inform you that the water treatment unit has been working perfectly and to

our full satisfaction ever since its installation.

Only a short time after that we observed that we no longer needed acetic or absorbic acid in

order to clean the showers and shower heads in out hotel, which has more than 65 guests

rooms, since the scale that builds up now is no more than a layer which is easy to wipe off. Due

to the fact that the efforts employed at maintaining the sanitary facilities can be kept to a minimum,

and resulting from the smaller electricity consumption, we are able to economize.

Simultaneously, we also make an active contribution to environmental protection by

renouncing on aggressive cleansing agents.

We are glad to own a water treatment unit that is compatible with the environment and which

renders the optimum output at low running costs (approx. 10 € on electricity costs/year).

Moreover, this unit has finally provided us the solution to a problem we had been confronted

with day by day and which was difficult to put up with.

Given our satisfaction it will always be a pleasure for us to recommend your company and your

product to other clients.

Sincerely yours,

Horst Schneider

Installation purpose

The results

One month after the Vulcan S10 was installed, we

opened the sewage outlet of the Chinese kitchen,

and found that the scale scrap came out. At the

same time, we compared the sewage outlet of the

western kitchen without Vulcan, there is no scale

coming out. The hotel manager is very satisfied

with the results and is making a new purchase.

The two steamers in the Chinese kitchen had been

scaled badly, they had been corroded and damaged

in 2 years. The client used to clean with acid once a

month, but the steamed food had the taste of citric

acid, and the acid would even damage the equipment.

Therefore, the client is looking for an efficient way to

remove the scale without bad odor after cleaning.

Vulcan S10 was installed on the main water line of the

Chinese kitchen.

The scale scrap came out of the steamer in the Chinese

Re: Letter of recommendation from Hotel Q!

Dear Mr. Christiani,

It is a pleasure for us to inform you that we have been very satisfied with the Vulcan descaling unit with

which you have supplied us.

As we are engaged in the hotel business and committed to cleanness, doing our best endeavors to combat

lime-scale is all the more important to us. In respect with the daily cleaning of the guest rooms as well as the

hotel facilities in general it is of paramount importance to maintain a high level of cleanliness, and the unit

you have provided us with helps us a lot to attain this goal.

The Vulcan S25 unit makes the daily cleaning of our hotel facilities easier and also allows us to save a lot on

cleansing agents for it is no longer necessary to use as much of them as we used to before.

I would like to single out for praise the fact that the scale converted by this device no longer settles on fittings

and panes of glass as it usually did before. Which enables us to maintain showers and fittings free of limescale

without any trouble.

Therefore, our hotel will gladly recommend this unit to other clients. We would also like to thank you for

granting us a trial period to test your device.

Yours sincerely

Quest Green Solutions

The Vulcan Descaler

P.O. Box 6662

Santa Rosa, CA

To the Quest Team,

We have sent you this letter to advise results after

purchasing the Vulcan 5000 from your office. We are an

18‐room motel located in the town of Cache Creek,

British Columbia, Canada; approximately 4 hours drive

north east of Vancouver, B C.

We purchased your product due to the continuous hard

water problems related to cleaning issues and hard

water build‐up. Our most obvious problems were in our

bathrooms where we found after a few years it became

impossible to remove hard water build‐up on and along

and close to the caulking areas of bathtubs and the

surround shower walls. We found that after 3 or 4 years

we would have to replace the surround shower walls.

The toilets constantly had waterline and water fall stain build up in the bowl, the bathtub and bathroom sinks

and taps also displayed hard water stain. Our guest room water glasses despite putting them through a

dishwasher would not come clean, typically they would display blotching or drips drying with mineral build up.

Our white linens did not stay "clean white" for long and displayed a darkened white after a couple of months.

Our hot water tanks and hot water copper lines continuously had to

be unsoldered at elbows and joints every few years to clean out the

scale‐ encrustation build‐up as the water pressure to the rooms lost

pressure.

When we first had a look at the elbows we were horrified to see just

a little more than a pinhole in some of the water lines getting

through. Our guest room kettles had a build up of minerals that were

obvious to the point where we would have to have to flush them out

on a regular basis.

Upon purchasing the Vulcan 5000 the first thing we noticed was that it really was easy to install with no

hidden surprises. Within a few days we noticed that the guest room water glasses were truly sparkling clean,

no blotching, all crystal clear. We were very happy with this result. The chamber maids have reported back

that the taps and faucets are easier to clean and I must say they do appear shinier and clean, although we

expect as time goes by they will become cleaner and newer looking.

The blotching in the tubs and surround walls has improved all though the best test will be to see what happens

in a year from now and on new installs. Although its difficult to tell at this early stage we assume the lines will

start clearing over time given the results we have seen so far. Typically the signs of severe hard water build‐up

start with turning on a tap in our laundry room and after a short period without adjusting the tap flow, the flow

gets less and less. We then start the process unsoldering and cleaning out the pipes manually. We expect this

process will now not be required. We have had the Vulcan 5000 in place now for just a short period of time

(month and one half) and are definitely pleased with the quick results so far.

Sincerely,

Hal and Karen

Dear Christiani Wassertechnik GmbH (CWT),

Due to the shower head scaling problem in Changping student dormitory in

Beijing University of Chemical Technology, the water was getting reduced after a

month, and the shower head was blocked completely after two to three months.

The scale was very hard, so we even had to use the 1.8mm driller to remove

it. In addition, the drinking water heater in the student dormitory was scaled

badly, two heating elements were completely scaled and no longer useful after

one semester, we had to hire cleaning workers regularly, and the damage rate of

heating elements was extremely high.

When I saw Vulcan products introduced by your distributor-Beijing North Xinhu

Mechatronics Co., Ltd, we doubted if such a simple product could solve our scaling

problem. Let's try and see.

We installed 2 Vulcan to test: one S25 for shower heads in the student bathroom;

one S10 for heating elements of drinking water. After 2 months, no scale was

found on the shower heads, only saw a thin layer of white membrane, and it was

easy to remove. Also, the scale of heating elements were significantly reduced,

Vulcan greatly extends the time of manual cleaning.

Through this test, we are very satisfied with Vulcan products with no doubts.

Strongly recommended!

Models: 2 x S100 in hotel’s main hot water lines

4 x S500 for cooling towers

Installed by: InterClima

Installation purpose

Most of the hotels in the area of Bávaro/Punta Cana in

eastern Dominican Republic depend on ground water wells

for their domestic water supply, using traditional water

softening equipment to reduce the scale and hardness of

the water. The fact is that some of these resorts have very

poor maintenance resulting in extensive scaling of cooling

towers and domestic hot water piping and equipment.

The results

The project began with a mechanical room energy

audit resulting in a great opportunity to upgrade the

existing equipment with a very short payback period.

The original installation was sold with an estimated

payback of less than 2 years. To our customer’s happy

surprise, the actual payback was 9 months! The hotel

maintenance manager is very impressed with the

performance of the Vulcan systems, this opened up

many additional opportunities including the subsequent

chiller and cooling tower replacements.

Before Vulcan S100 was installed in hotel’s main hot

water line, the storage tanks had a solid 3 cm thick

scale layer inside them and the pumping pressure from

the booster set was at maximum while being unable to

deliver adequate water pressure to the end of the line

hotel rooms. After the 3 months period, an inspection

of the inside of the storage tanks revealed that the

scale layer was soft allowing them to mechanically

clean them removing most of the calcium deposits.

Other the following 12 to 18 months, the distribution

lines also cleared up resulting in much improved flow

and lower pumping costs from the booster sets.

The manager was instrumental in the approval of the

resent trial installation of an S250 in the Royalton White

Sands (Jamaica). We will continue to use the Barceló

success in our future presentations.

Asia to be awarded the highest level of

Platinum Green Building certification

from LEED (Leadership of Energy and Environmental

Design) that serves as the prototypical building

in Thailand for energy conservation, harmonious

coexistence of industry and the environment and

optimal utilization of resources.

Installation purpose

Before Vulcan was installed, the client used ozone water

system to treat the condenser, but they still found massive

scales in the basin of the cooling towers. They collected

the scales from the basins and weighed them, there were

around 150 kg (average) of scales every month.

The results after 4 months

Vulcan was added together with the ozone system

to treat the water. After 4 months, the approach

temperature of the chiller has been reduced, so that

the energy has been saved from the machine. Also, the

scales from the cooling tower basin have been reduced.

Vulcan S250 and X-Pro 1 were installed on the main

return pipes of the condenser.

7 cooling towers were treated with Vulcan.

RE: Vulcan Descaler as an alternative to chemical based cooling tower treatments

Dear Dick,

For the past two years, we have selected several of our existing customers and offered them the opportunity to

have us install the Vulcan Non-Chemical Unit on their cooling towers, for the purpose of evaluating corrosion,

scale and bacteria rates versus a traditional chemical treatment program.

We have installed 5 x Vulcan S25 & 2 x S10 units all in the upper New York State area.

Based on standard water test analysis, including Corrosion Coupon Testing and regular Bacteria Dip Slide

results, we have concluded that the Vulcan Non Chemical System has been able to provide similar results, to

those achieved using a chemical based treatment program.

Vulcan anti-scale system

Dear Mr. Vestad,

I have noticed a definite improvement in the operation of our boilers. Typically, we would have several cooling

coil plug ups during the hot weather season (a greatly extended season this year) and since the installation of

the Vulcan, we have had zero plug ups and that translates into the saving of many hours of down time.

Based on that saving alone, the Vulcan has already paid for itself.

An additional benefit has been in the greatly reduced amount of cooling tower maintenance. The calcium

buildup has been miniscule and the little bit that has accumulated can be easily washed away with a garden

hose and nozzle.

I have also noticed a huge reduction in the iron stains in the bathroom fixtures here at the factory as well

as at home where I installed the second unit. At home, I eliminated my water softener that was running on

potassium due to the ancient iron pipes that run all through the house and barn.

The water seems to feel and react just as well with the Vulcan as it did with the softener and I no longer

need to buy the expensive potassium and break my back lugging around the heavy bags to reload the water

softener. I don’t mean to sound like a commercial for the unit, but those are the honest facts and observations.

Please feel free to stop by the next time you are in the area.

Kindest regards,

Vulcan Effects on Cooling Towers

USA

Data and Observations of the Effects of the

Vulcan Electronic Descaler on Cooling Towers

Installation site:

The unit was installed on the 10 inch diameter line

that feeds twin cooling towers (CT-1 and CT-2) at

the FAMU/FSU College of Engineering.

Model installed:

Vulcan S250

Objectives:

The objectives are to prevent scale buildup on the cooling

towers, remove the existing scale, eliminate the need for

chemicals or time-consuming cleaning procedures, and to

reduce energy costs.

History:

The maintenance for these cooling towers previously

involved continuous injection of descaling chemical

cleansers. The use of these cleansers was discontinued

over a year prior to the installation of the Vulcan. In that

time, the cooling tower flutes became encrusted with both

scale and biofilm. Throughout the time period described

below, there were no cleaning procedures in place with

these cooling towers besides the treatment provided by the

Vulcan.

Observations over time after the Vulcan

Installation:

Between the time of the installation on July 16th and

examination on August 1st, the green biofilm had begun to

recede and gradually disappear. The next visit was about 3

weeks after the installation, on August 9th. At that point,

the green biofilm had been further reduced and the scale

deposits had begun to separate from the flutes in coin-sized

flakes.

By August 20th, about a month after installation, the

green biofilm had almost completely disappeared from

the surfaces in contact with the Vulcan-treated water. The

flakes of scale previously observed had fallen off in most

places. The cooling tower flute surface area covered with

scale deposits had been decreased by over 60%.

We are very optimistic about continued improvement with

this application. In addition to these observations, water

quality measurements were also obtained from each cooling

tower and are summarized in the following charts.

The Vulcan does not change the water quality beyond its affect on its propensity to cause scale buildup. As illustrated below, the

pH, conductivity, dissolved oxygen level, and turbidity remained relatively constant during observation from before the installation

to over a month after. Temperature is included, because of its affect on the other measurements and seems to correlate with the

Before the Vulcan was installed, there would be a

12mm calcium buildup in the nozzle by this time

and they would exchange it with one that had been

acid cleaned.

The maintenance man held the cleaned one in one

hand & the one he had just removed, in the other

hand. He was showing them to an engineer and

held out the cleaned nozzle and said he was going

to install it on the wash station - The engineer said

"Why would you install the dirty nozzle instead of the

clean one!" Everyone was amazed - 35 more Vulcan

S25 were ordered after this test.

Mister,

W. Kurt

Following our discussions at the Salon de l‘immobilier Neuchâtelois, we agreed to install the Vulcan

model S100 on our premises for a five-month test phase as soon as our ice period began operating

in August.

The defined objective was mainly intended for the dumpsters of our two ice resurfacers, which are

filled with snow all day long and therefore subject to weekly descaling.

After a few weeks, we noticed that the scale adhered less. This makes it easier to clean our machines,

saving us time and products.

The test carried out allowed us to take the time to compare the positive effects of the Vulcan S100 on

our installation and that the objective set was achieved.

We would like to take this opportunity to thank you for your warm cooperation and extend our warmest

greetings to you, Sir.

Ralons Lavandería Laundry Services

Spain

Dear Sirs,

After multiple problems with scale build-up in our irons and laundry

equipment we decided to try and solve this situation. After much

research,we finally found the solution we were looking for. We chose

the innovative line of water treatment, Vulcan. The Vulcan S25 unit

was installed.

Up until now, the results obtained have been entirely satisfactory; not

only because the scale does not stick to surfaces anymore, but also

because of the raised quality of the laundry which has a less-abrasive effect

on the clothes. This has helped increase our service quality and customer

satisfaction.

For the above reasons, we certify the complete effectiveness of the Vulcan

S25 device installed in our company.

Sincerely,

Testimonial with Jamie Cavey

Hi, my name is Jamie Cavey and I operate the only commercial laundry in Pilbara -

The Pilbara Commercial Laundry Services. We are a mid-size operation that specializes in

the laundering of hotel linen, mine site linen and work clothes.

Living in a hard water area like Pilbara means we have ongoing problems with calcium

build up in our piping and air-conditioning systems. The calcium sticks to the heating

elements and the whole internal section of the hot water system becomes completely

clogged with calcium.

Twelve months ago we installed a German made CWT Water Treatment System from the

team at Southern's Water Technology in Bunbury and immediately we noticed a significant

reduction in the build up of calcium.

I believe we have quadrupled the life span of our evaporated air conditioner and we haven't

had to replace our hot water system for more three years.

Without the CWT Water Treatment System we would be replacing our hot water system

every two years at a cost of more than $10,000.

There is no doubt the CWT Water Treatment System will prolong the life span of your

piping and hot water systems and evaporative air-conditioning units.

After the treatment, the adhesiveness of the crystals is reduced so that scale is unable to

form in the pipes.

You can actually see the calcium slowly breaking down through the drainage system.

Sincerely,

Jamie Cavey

Christiani Wassertechnik GmbH (CWT)

Köpenicker Str. 154

10997 Berlin

Germany

Dear Mr. Christiani,

Thank you a lot for sending me the stronger electronic system, which I installed immediately. I noticed

that the drinking behavior of the animals improved promptly. I can give you more details after a longer

observation period. Now about the promised observation of the CWT water treatment device:

After 2-3 days of the installation, it was remarkable that the lactating cows were permanently drinking

from the drinking trough and that therefore the milk production also improved after 14 days, which

again led to higher weights of the piglets (before: ca. 7 kg, now: 8 kg). This continued for several

months.

Furthermore, we observed that scale and biofilms in old pipes for liquid feeding dissolved, leading to

an improved feeding behavior of the fattened pigs. Moreover, we used to have trouble with flank

abscesses due to biofilms that were probably caused by bacteria discarding endotoxin. This

progressively improved with the use of CWT water treatment.

I can also tell you about a cow farmer whose pipes were not clogged anymore after the installation of

CWT products. Before, he had to flush the pipes every 4 weeks with air and water to make sure the

cows could get enough water through the pipes. He could furthermore observe that the biofilm on the

high-alloyed steel drinking trough dissolved after 14 days. After about 4 weeks, the farmer also

reported that the cows produced about 0.5 L more milk per day.

Negative observations:

The next year in February, I started to occasionally add acids in the tubes with the consequence that

the positive effect of the CWT water treatment mostly vanished. Furthermore, new biolfilms built up in

the pipes, which I could make visible by flushing the pipes. The animals began to show more flank

abscesses and ear necrosis again. This improved again after the flushing in the beginning of June.

Then, on 19 July, I installed the stronger electronic system. Since then, I have the feeling that the

livestock has stabilized and has become more vital.

I hope I can give you more positive news soon and that I can tell you, whether an occasional addition

of acid to the water system is possible without damages, since it is common practice to use acidy

products in farms holding pigs and turkeys.

Please don’t hesitate to contact me for further questions.

Best regards,

Hubertus Fasselt

cleaning is much easier than without Vulcan – with less need of

chemicals. Also the scale depositis of the cisterns and shower

heads are much less, so we have less maintenance costs. We

recommend your Vulcan system and we will install more Vulcan

systems in further of our sanitary stations in Switzerland.

Dear Mr. Christiani

we are a facility management company responsible for the maintenance and repairs inside the

St Joseph Hospital in Berlin. Due to the hard water in Berlin, we used to have very bad problems

with scale incrustations on the sanitary equipment. The maintenance and cleaning of the 2,500

showers and bathrooms alone was at a very high cost.

We have had the Vulcan S 250 installed inside the hospital now for a couple of months. We can

identify a considerable benefit of the unit installed. We can barely see any scale deposits on the

shower heads any more. This saves manpower and costs associated with exchanging sanitary

equipment.

We can honestly recommend the unit installed by CWT GmbH.

received positive feedback from our customers in view of the effectiveness of the system -

patches of limescale which could previously only be removed by chemical detergents can

now simply be wiped away with a cloth. What is more, the use of the system has notably

reduced the calcification in the heating of electrical equipment (e.g. washing machines,

dishwashers, kettles etc).

We wish you and your company furthur success and in the above mentioned matter would

like to thank you for a successful collaboration.

CWT - Physical water treatment system

I‘ve been in the plumbing industry for 32 years and currently have five staff working for me at Phillip Best

Plumbing in Western Australia. Since becoming available in Australia, we‘ve purchased a number of CWT

water systems to stop calcium deposits building up in a range of different piping systems. These deposits

create many unwanted effects such as clogged pipes and irreversible damage to pipes and other plumbing

parts.

I found the CWT water treatments to be very effective in high temperature heating systems such as

commercial combustion ovens in restaurants and even in a very high temperature heating system at a local

abattoir. There are also huge time savings associated with CWT water systems. Installation time is cut by

at least 90% when compared to similar units. The units, which are made in Germany, are also at least 50%

cheaper than other units currently on the market.

The units, which allow scale particles to be washed away, are not only proving to be successful in commercial

and industrial applications, but in private homes with scale and rust problems. I installed a CWT system to

protect the hydraulic heating system, which lies under the cement slab of our home.

CWT has been a great cost saving unit initiative that will protect your piping system from ongoing scale and

rust problems.

Reducing RO Membrane Replacement Frequency with Vulcan

China

the Improvement Project for Reducing RO Membrane Replacement Frequency

Installation details

Installation location:

A factory in Inner Mongolia Huomei Wheel Manufacture

Co. Ltd., which produces aluminium alloy wheel.

Vulcan was installed in the painting workshop, for the

pure water section. Pure water is produced by RO

membrane (reverse osmosis membrane).

Scaling problems

Before installing Vulcan, adding scale inhibitor

was the only descaling method, and the RO

membrane would be replaced every 2-3 months,

sometimes even more often: every 1-2 months!

Each replacement costs about 9,000 USD.

Installed by:

Suzhou KaiEnSheng

Results

Installation model: Vulcan S10

Pipe size , capacity: 65 mm, 15 m 3 /h

About Huomei Wheel Manufacture Company

Since the Vulcan was installed in April 2017, the

RO membrane has not been replaced until now

(October 2017), and the use of scale inhibitors has

also been reduced by 50%. So far, the estimated

cost savings are around 25,000 USD.

Located in Huolinguole Industrial Park, Inner Mongolia.

It is one of the largest aluminum wheels manufacturer

in northern China.

A letter from production department of

Huomei Wheel Manufacture Company

From May 2016 to January 2017, 5 sets of RO

membrane were replaced, they cost 50,000 USD.

The issue is urgent.

We found that the problem comes from the water

quality. Suzhou KaiEnSheng recomands Vulcan

for us to try. Surprisingly, the effect is very good.

Vulcan was installed on April 6, the conductivity

after the three-stage RO membranes were: 17.1,

22.7, 21.5 (μ-Siemens/cm) on the day. Over

4 days, we already saw noticeable effect. We

measured the conductivity again on May 4 after

the three-stage RO membranes were down to

11.5, 11.5, and 11.6 (μ-Siemens/cm). We will

keep tracking the effectiveness.

The Vulcans not only save a lot of water treatment costs, bring a significant reduction of filter cloth (cost), but

also reduce the workload for workers to fight against scale.

Water treatment system by CWT Germany

My wife and I live on a 5 acre property at Gelorup, 20 minutes south of Bunbury in Western

Australia. Our local water causes enormous problems with our reticulation system. Large quantities

of iron sludge and chips would build up in the piping system and block the solenoids and individual

sprinklers. The situation was getting us both down. It seemed like the sprinklers were continually

blocked and I was replacing the solenoids every six months.

Within three months of installing the CWT water treatment system the rust residual and sludge disappeared.

I was staggered by the results. The pipe was completely clear and there were no signs

of the iron scale at all.

A reliable and clean sprinkler system is very important for us to maintain a healthy garden which contains

more than 200 rose bushes and half an acre of trees and cottage garden. Our horse paddocks are also

under reticulation. The CWT system has saved me an enormous amount of time and money and I’m no

longer cleaning sprinkler heads or replacing the solenoids in the reticulation system.

The results have been so successful we are now planning a major expansion of the

garden and bird aviary. I would recommend this product for anyone who lives in a hard water area

in Australia. They’re simple to install and maintenance free.

Test of the electronic water-treatment system Vulcan 5000 for the cooling system of the

laser Innova 90-K of the company Coherent GmbH (user report)

Dear Mr. christiani

Referring to our telephone call on the 18th of December, i would like to send you a

description of our trial of your electronic water-treatment device Vulcan 5000.

the system Vulcan 5000 was installed at the end of March in the coolant inflow of a crypton

gasions laser innova 90-K manufactured by the company coherent gmbh, supplied with water

from the system of mains, to reduce or even avoid lime deposits on the ceramic covering of the

laser tube. over the past years we constantly had difficulties with laser tubes which were not

in working order any more and consequently had to be replaced due to thick lime deposits on

the ceramic of the tubes through which the coolant flows with approx. 9l/min and a pressure of

approx. 2.5 bar and at the same time heats up to a temperature between 60°c and 70°c

depending on the gas discharge electricity (tube electricity) between 30 a and 40 a.

the system Vulcan 5000 is an economic alternative to expensive heat exchangers, i.e. closed

circulations of coolant with treated water. these heat exchangers cost about 5,000€. the

device Vulcan 5000 has been used on a trial basis since the end of March to treat the coolant

of our gas laser. on the 12th of December the company coherent gmbh checked the laser

tubes for lime deposits on the ceramic surface. no lime deposits were detected, therefore, it is

in all a positive result .(see

service report of the company coherent gmbh enclosed).

During the test period the laser was in operation approx. 200 hours with a laser tube electricity

ranging from medium to maximum and with operation times between four and eight hours. these

operation periods and the accomplishment required correspond to the normal use of the laser in

our fluorescence microscopic experiments. laser tubes previously used in a similar way, which

worked without a treatment of the coolant, showed considerable lime deposits.

Concerning the effect of the water-treatment device

Vulcan 5000“

Test subject: water treatment device "Vulcan 5000"

Manufacturer:

Christiani Wassertechnik GmbH (CWT)

Heinrich-Heine-Str. 15

D-52249 Eschweiler

Test instruction:

A test should be carried out to determine whether Vulcan 5000 can reduce lime

deposits in water pipes and household equipment in a purely physical manner

without altering the water chemically.

Experimental demonstration of function:

The effect was verified in a heat exchanger arrangement using two identical testing

units. Water was withdrawn from the water pipes simultaneously upstream and

downstream of the device to be tested and calcium precipitation forced in the heat

echangers.

As lime deposits increase, the flow of water decreases. The more water flows

through the experimental arrangement, the smaller tendency there if for the water

to form scale on pipes and container walls. The test was carried out on the basis of

the practice-related water withdrawal of a four-person household with the additional

regular withdrawal of five litres of water at half hourly intervals for a total of six weeks.

This test showed that the tendency to form lime deposits is reduced considerably by

the “Vulcan 5000” water-treatment device. In addition, the effect continues for some

days after “Vulcan 5000” has been switched off. Seemingly, the effect is not only

limited to a certain part of the pipe, but also passed into the water flowing nearby

sections of the pipe.

Results before and after the Vulcan installation

Kitchen Kettle

Before (without Vulcan): A layer of scale had accumulated at the

bottom over time, it was impossible to remove it with a plastic spatula.

We could only leave vinegar to let it act for a long time, so that the

scale could be removed.

After (with Vulcan): Scale is easy to be removed, even with a

finger or a damp cloth.

External surfaces of pots and pans

Before: If you do not wipe off water right away, the water would leave

spots and it would be difficult to remove afterwards. You can only

clean with dishwashing detergent again, and wipe off water without

delay.

After: Even the pot has been dry for 30 minutes, it is still easy

to remove spots with a damp cloth. If it is left to dry for a longer

period, e.g. 1 night, the spots disappear after rubbing the surface

for several times with increased pressure but still without

detergent.

Sink (stainless steel)

Before: Quick greasy fouling, especially after removing residues from

cooking oils with rinse water from cooking tools. Rough sponge and

brush with degreasing detergent needed.

After: The degreaser is still necessary but the cleaning is easier

and less work.

Dishwasher (internal wall is stainless steel)

Before: White layer of scale adherent (on the bottom and on the door)

was difficult to remove; anti-scale product was required.

After: The white powder on these surfaces is easy to remove

with a wet sponge (no special cleaning product).

Chrome faucet

Before: Scraping scales with a knife onto the spay heads was necessary

because the outlet holes of the spay heads were stuck by scales.

After: If scale builds up on these elements, it can be easily removed

without an anti-scale product.

Filter holder of faucets and filters (kitchen and bathroom)

Before: Limestone was strongly stuck on the circumference of the

rings and also visible in the plastic filters (inner side). To remove the

scale by soaking in vinegar is necessary. The outlet holes in the spray

head (kitchen) were frequently blocked by hard-to-remove scale

deposits.

After: No deposit was found inside the filters or on the outside

rings. The water comes out of the shower head without any

obstacle, and no new deposit accumulates in the holes of the

spray head.

Worktops (granite surfaces)

Before: Accumulation of a layer of scale left by the water around the

tap; After drying the surface appeared dull and dirty. No anti-limestone

(acid) product should be used on this mineral surface. Natural stone

care products are only effective on a scale-free surface. Scraping of

the stone surface with a metal spatula after using the steam cleaner

at the maximum pressure.

After: The cleaned and treated surface regains the original

shine and brightness; Its maintenance is no longer a problem:

the limestone powder is easily removed with a damp cloth.

The stone care product is used from time to time with better

efficiency.

Washbasins (bathroom)

Before: "Rust" fast and sticky. The deposits could only be removed

with an abrasive sponge + degreasing detergent and sometimes an

anti-scale product.

After: The deposits are easy to remove with a damp cloth. The

use of soap only serves to ensure the hygiene of the surfaces.

Drain pipes for washbasins

Before: A cylindrical brush (white synthetic threads) was pushed in

rotation and under running water to the bottom of the collector, was

charged with a black sludge deposit when removed from the pipe

(weekly cleaning). It is still a proof of this surface bonding power that

characterized "hard enough" water.

After: When the brush is removed, the threads return to a state

of whiteness almost without black deposits.

Toilet (Ceramic)

Before: Even after using the w.c. brush, the "traces of marks" had

a tendency to clog especially to the bottom of the bowl. "Hygo WC

maximum power gel" cleaning products were necessary to ensure

proper hygiene.

Fittings

Before: The deposits of scale were less around these elements

because they were less accentuated on the ceramic than on the

granite. An anti-lime product helps to eliminate scales around the

linings (easy knife scraping).

After: These spots are now easy to "erase." Even if it is

necessary to use cleaning products for reasons of hygiene or

for routine maintenance, it still saves the use.

After: Wet wiping is already sufficient, even without anti-scale

product.

Shower heads

Before: The water outlets were often blocked by scale deposits.

After: There are no more obstructions and the water flows

smoothly.

Shower cabin (glass)

We have not noticed a great difference between before and after at

the level of the glass walls: glass is the material on which the scale

attaches the least, especially since they are vertical walls on which

water flows easily. Another co-owner found that the stains on the

glass walls were easier to remove than before.

Shower enclosure frame (aluminum)

Before: It was necessary to scrape the deposits of scale

accumulated at the junction of the shower tray with the knife,

an anti-lime product (acid) can not be in contact with this metal.

After: The deposits are removed with ease.

Evaporation of water in a saucer and a glass

A) Glass saucer with flat bottom. Before: The scale clogged strongly to the bottom and vinegar was necessary to remove it. After:

Scale still clings to the bottom, but can be removed only by rubbing, if necessary with a plastic spatula, but without using vinegar.

B) Water glass. Before: The scale was formed on the wall of the glass, difficult to remove (vinegar necessary). After: The limescale spot

is less broad and less compact, but it is still difficult to remove without vinegar.

These scenarios are not the same as water flowing along a vertical glass wall and leaving few traces (walls of the shower cabin).

Conclusions

After Vulcan was installed for 1 week, in general, we quickly noticed a

marked decrease of adhesive forces of the water on most surfaces in

contact with water over a prolonged period. The comfort provided by

this limestone converter is very appreciable compared to the previous

situation.

Another advantage of this system, and not the least, is its

excellent efficiency / price ratio; There will be no additional

charges thereafter and its consumption of electricity is

insignificant. It is more appreciable while the loads of the

building always tend to increase.

Our wish was to find a solution to the problem, not by totally eliminating

the scale, but by finding a way to convert its physical structure so that

it can improve the cleaning effort and protect the devices without the

addition of chemical substances.

This device is an excellent compromise for solving the problems in our

building caused by the hard water.

We have no particular interest (financial or otherwise) in

promoting this system and we also needed evidence of its

effectiveness, which we have received from these tests.

We firmly believe that this is the most advantageous system and

strongly wish to keep it.

Maintenance is simple because no maintenance is required after the

unit is installed. There is no dependence on products to be added and

which must be managed throughout the year. The composition of the

water remains unchanged, which is a strong positive point for health.

Observations after Vulcan disconnected

15 days were needed to make the first observations:

- Aspect of the water: the water appears heavy and oily again.

- Water has become aggressive on the skin (shower).

- The scale sticks again on the kitchen tap fittings.

After 4 years of building pipe expansion, it took only one week

to make initial observations of the efficiency of the VULCAN

descaler.

But the time to reappear of scale deposits or water effects on the

skin after the system was shut down was twice as long.

- The scale is deposited again on the granite and it is difficult to

remove.

- The scale is deposited back to the bottom of the kettle and can not

be removed with a hand or a damp cloth.

- The internal surface and the dishwasher tank are again covered

with scale.

- The clogging of bathroom sinks has begun to occur again (the scale

adheres to the ceramic).

One of 7 cooling towers servicing the Mall's water

cooled package air-conditioning systems. The

cooling tower selected is a 408TR system containing

45 m 3 water volume with a water flow rate of 318

m 3 /h in an open circuit system.

February 2014 - February 2018 (4 Years)

PT Biosolutions Indonesia

Vulcan S500 was located inside aluminum box

and installed on a cooling tower main pipe in

Supermal Karawaci.

Inspections

The photographs show that the refrigeration condenser tubes, from the beginning to the end of the trial

period, were "as clean as new".

Please note that for 4 years of 365

days continuous operation, there has

been:

• No chemical water treatment.

• No bleed off of waste water.

• No cleaning of condenser tubes.


• No water treatment specialists

employed.

• Copper tubes in the condensers stay

very clean – without scale.

• No cleaning of the cooling tower

inside surfaces.

First Inspection: March 4, 2014.

The heat exchanger tube plates were

removed to reveal the inside surface

of the copper tubes. Since these tubes

had recently been manually cleaned,

virtually no scale was present, as is

obvious on this photo.

Last inspection: February 12, 2018

at the end of the 4-year trial

The inside surfaces of the copper tubes

show zero additional scale formation

after 4 years in the test period.

Significant findings as a result of the 4-year field

tested trial:

Scale build-up did not take place. During this 4-year trial period, no

scale formation was found on the condenser heat exchanger copper

tubes of the system.

• We have found conclusively that EC (Electric Conductivity) levels

of up to 10,000 µS/cm can be safely ignored. Similarly, high TDS,

metals, anions and many other substances in cooling tower water

can be ignored when Vulcan is used. Cooling tower water blow

downs are vastly reduced because with the Vulcan the maximum

EC limit increases from 1,200 µS/cm in chemically treated cooling

tower water systems to the much higher limit of EC 10,000 µS/cm

for the electronic method of cooling tower water treatment.

At the new 10,000 µS/cm EC limit, the need for cooling tower water

blow down will likely be reduced from almost daily to once or twice

per year.

• No system maintenance was required.

• All AC compressors ran entirely at clean condenser efficiencies.

• R22 refrigerant gauges on all condensers remained at constant hot

gas head pressure.

Summary of Benefits:

• Large savings on chemicals. The complete elimination of chemicals in this cooling tower operation during the field

test supports the fact that Vulcan is “eco friendly” and would meet the Leeds and Green Mark Building Criteria required

for “Green Building” designation anywhere in the world. Enjoy the benefits of a world class, sustainable and

“Green” Cooling Tower!

• Huge savings on blow down water consumption. Significant energy and water savings due to clean condenser tubes

and no need for water blow downs below electric conductivity 10,000 µS/cm levels with the electronic cooling tower

water treatment system – representing alone a saving of virtually all previously wasted water due to blow downs.

• Savings on payroll – no operational stoppages required for condenser cleaning, less testing and fewer inspections

needed.

• Savings on supervision – engineers appreciate the “set and forget” of this automatic water treatment system.

Frequency of inspections and laboratory expenses for cooling tower water testing are reduced due to the safety and

reliability of the electronic systems.

Scale formation was eliminated. Refrigeration compressors operated at peak efficiency due to no scale in the condensers.

• Rust prevention in iron pipes is an added benefit of the Vulcan system.

2-1 cooling tower A: Makeup water piping size is 50A.

2-2 cooling tower B: Makeup water piping size is 50A.

1 cooling tower C: Makeup water piping size is 50A and circulating piping size is 80A.

Model installed:

Vulcan S25

(water treatment capacity: 25 m3/hour)

Vulcan installed on the

makeup water piping (50A)

Vulcan installed on the

circulating piping (80A)

Date installed:

For the cooling towers A, B, and C: July 22, 2006

For the cooling tower C: October 6, 2006

Used for cooling towers A, B and C Used for the cooling towers C

Objectives:

1 To prevent scale buildups on the cooling towers.

2 To reduce chemicals used for water treatment

(measure for complying with ISO 14001)

3 To save the energy cost by preventing the deterioration of the heat exchange effectiveness

Verification of the effectiveness:

After installation of the Vulcans, the statuses of the cooling towers A, B, and C were inspected without using

any water treatment chemicals. Even after elapse of approximately six months, almost no scale build-ups

were observed inside the refrigerators and the heat exchanger tubes, and no water pollution warning was

displayed. (Usually, without water treatment chemicals, the water quality is deteriorated and water pollution

warning is displayed.) Silica adhered on the cooling towers was easily removed with a finger. With these

results, the effectiveness of the installation of the Vulcans could be confirmed.

Remarks (Summary)

The water treatment system, Vulcan, has the following features: (For details, refer to the brochure attached.)

Vulcan changes only the crystal structure of scales without changing the quality of water. Therefore, nothing

is added or reduced to or from the ingredients of water. The water through Vulcan is soft and has an increased

permeability. Vulcan can be used as better cooling water.

(*) The effectiveness of the water treatment in the water supply line will last for 2-7 days and for approximately

2 km in distance.

Major features include:

- Prevents buildups of rusts and scales

- Makes cleaning in the kitchen and bathroom much easier (toilets, showers, tiles, joints, etc.)

- Drastically reduces the clogging due to oil balls

- Eliminates the necessity of strong chemicals for removing scales.

- Eliminates the necessity of additives.

- Does not change the water quality.

- Prevents the clogging at the time of drainage
